Strange, usually all the model numbers you guys post here don’t jive with US official dahua part numbers. That cam is available through my distributors and sure enough it lists that pole number but they don’t list the mount at all. I wonder if either of these might work for you?
that is a good question
I bought that camera so I can take down and send in my other cameras that has fogged up lenses I have 5 of the IPC-B5842E-Z4E that suffer from that issue
